MARKING-MACHINE.

Specification of Letters Patent.

Patented Jan. 28, 1919.

Application filed January 18, 1918. Serial No. 212,483.

To all whom it may concern:

Be it known that I, ALBERT A. WATER- MAN, a citizen of the United States, residing at Mansfield, county of Bristol, State of Massachusetts, have invented certain new and useful Improvements in Marking-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to marking machines, that is machines used to stamp a die eitherin relief or in intaglio with marks or designs. The machine is particularly adapted for marking or imposing in or upon cylindrical rollers or dies any marking or design desiredthe work being forced into rolling contact with a vertically reciprocating die during the operation, and released at the end of the operation.

The parts may be reversed and I may use a cylindrical rolling die and a flat piece of work, to be embossed or marked, and varione other changes may be made.

In the accompanying drawing:

Figure 1 represents, in perspective, view of the machine.

Fig. 2 represents a corresponding view from theother side.

Fig. 3 is a top plan view; and

Fig. 4 is a view showing the cylinder.

In the drawing, 1 is a driving wheel for my. device, secured on the shaft 2 mounted upon the fixed frame 10 of the machine. On the same shaft is a gear wheel 3, meshing a side 4 with gear wheel 5, mounted uponshaft 1,

also on the frame of the machine. On the same shaft is mounted cam 6, which may be made upon or bolted, or otherwise secured to the gear wheel. It must turn with said wheel. Engaging with the periphery of said cam is one end of a tilting or walkingbeam lever 7, a roller 8 being provided for the purpose of reducing friction. Said lever is pivoted at 9 upon frame 10 through a standard 11 attached to or madeia part of said frame 10. The other end of said lever is in contact with the upper end of a slid-' ing block 12 provided with a friction roller 13, if desired. The face of this block holds or is provided with the lettering 14, or other design it is desired to roll into or otherwise create in the cylinder of steel 15, or other object being treated. This constitutes in effect the die, and it is substantially parallel with the face of the pressure or impression block. This block slides on standard 16 mounted fixedly upon frame 10, so as to be a part of the rigid structure, suitable dovetailed sliding ways being provided.

I provide at the other end of the machine a standard 17, in which is mounted a shaft 18 carrying a cam 19, arranged to contact with and move forward the pressure or impression block 20 mounted to slide in suitable ways 21, and provided with adjusting means in the shape of a screw 22 for adjusting bearing distance, in accordance with the size of the object for the smooth terminal portion or end 23 of the block 20. The cam 19 is provided with a suitable device to cause a dwell, as shown, so as to cause a period of rest in the movement of block 20. This is timed to correspond with the downward movement of block 12, the movement of the latter being across the face of block 20, carrying in its movement the steel cylinder 15 and rolling into it the desired pattern or marking.

On the shaft 1 I mount a cam 24 engaging the upper end of a vertical lever 25 pivoted at 26 in the frame 10; said lever being provided with projecting arm 27 and friction roller 28. The lever is thus rocked by movement of the cam. To this lever or pivoted arm 25, I attach at one of several indicated points, a connecting rod or pitman 29, which at its other end, is pivoted at 30 to an arm 31 on shaft 18. The arm 25 is provided with holes whereby connections of the rod 29 may be adjusted as desired. A spring 32 is provided for holding the arm 25 in position against its cam 24. I provide a spring mounted pivoted arm 33 upon which the work may be rested while the parts are moving to position. This cam is carried down by the rolling action against the spring 34: which spring, when the work rolls off the face of the pressure block, returns arm 33 to position.

I show at 36, mounted on the bar 29, an adjustable standard which may be used as a stop to keep work in correct position, if desired.

I show at 37 a roller adapted to take part of the weight of the horizontal moving pressure block, and 38 is an adjusting collar for the screw adapted to hold the pressure block against the cam. A returning spring 39 is shown in dotted lines for returning the sliding block 12. I provide my cams, of course,

with the necessary even spaces to produce required dwell. I

It will be seen that I have produced suitable adjusting means, and provided a strong,

simple, and sure machine, the parts of which cannot get out of order.

In operation, after the machine starts, a Workman standing near themiddlepf'the machine where the smooth end of the pressure block and the perpendicularly moving parts are, adjusts the soft or untempered steel cylindrical blanks one by oneupon the bracket 83; as the plunger descends each blank is caught, androllingover th'eface of the pressure block, receives its impression and drops out below into any suitable receptacle. The placing ofthe blanks must, of course, be timed to accord with themovements of the machine.

I may, as stated, at times make the cylindercarry the mark and impress it upon the vertical plate. The terms vertical and-horizontal, as used herein, are intended to desig nate direction ofmo'vement of parts'with relation to each other, and not particularly with respect'to the horizon.

Having thus described my invention, what I claim as new and desire to secure by Letters' Patent of the'United States is? 1. In a marking machine, in combination, a driving shaft, a reciprocating marking die, a walking beam, a cam on said shaft actuating said walking beam to reciprocate said die, a reciprocating impression block having a smooth face adapted to be advanced to a positionnear the-path of movement of said die, a cam, and connections between said shaft and said block whereby the movements of'the block are effected in timed relation to said marking die.

2. In a marking machine, in combination, a straight vertically sliding die, a straightfaced horizontally sliding impression die, and a device whereby the impression die may be moved to'positionwhile the marking die may be in ineffective position and may be held quietWhile the marking die is moved past its face, in order to'rollan impression into a blank between said moving die and stillface the parts all cooperating in timed relation, a driving shaft, a lever for each of said dies, and means whereby said shaft, through said lever, actuates said dies.

In a marking machine, in combination, a shaft, a cam on said shaft, a walking-beam, a reciprocating die member adapted to be -moved*by' said walking beam, a second cam,

an oscillating arm adapted to be driven by said shaft, a pitman connected'tosaid' armi an arm connected to the other end of said pitman, a shaft adapted to be rocked bysaid arm, a cam on said shaft, and a horizontally reciprocating impression block' adap'ted to be moved bysaid cam.

4:. In a marking machine, in combination,

a horizontally reciprocable markmgonimpression member having-a vertical face, a vertically reciprocating marking or impression member having" its moving" facearranged to move substantially parallel to the vertical face of the other member near the middle of the machine, means'whereby the horizontally movable member 'may be moved into and out of position, and means whereby when said member is in-posit-i'on 'it may be held stationary during movement of the other member, the sa'i'd 'means' allcoope'rating to effect the movements indicated in proper timed relation, and: a driving: shaft at one end of the machine, said means ex:-

tending fromsaid shaft to said markingand impression member to actuate the same.

In testimony whereof, I affix my signature.
